Displaying a message upon user registration
I have a question that I hope will be pretty simple for some of the WordPress Gurus out there.
I have a WordPress network and whenever a users signs up, I would like to show (on signup confirmation page) a message that shows the code:
<script type="text/javascript" src="
<script type="text/javascript">
SA.redirection_mobile ({nmobile_url :
"USERURL.mysite.com", });
</script>
**Note** that I am trying to display the user's URL that they just signed up with in the message.
Does anybody know how to do that without modifying any of the WordPress core?
Let me know if this is a little too vague, or if you need any more information.
Thanks, Keenan | <
> This action hook allows you to access data for a new user immediately after they are added to the database. The user id is passed to hook as an argument.
add_action('user_register', 'registration_redirect');
function registration_redirect($user_id) {
$url = 'PAGE_WHERE_YOUR_CODE_IS_DISPLAYED';
wp_redirect( $url );
exit;
}
placing that in your functions.php should work. This attempts to redirect the user after they register, i believe after they click the link in the email, which is what i think you were looking for. | stackexchange-wordpress | {

How can I let users access a specific attachment?
I'm trying to add a XML file to my site that users can access when I give them the url.
www.domain.com/blank01/blank02/file.xml
As of right now, blank01 and blank02 don't exist as pages. Down the road they will have content and links that eventually take you to "file.xml" and others.
But for right now I just want to put this file on my WP and make it accessible to my users when they go to this specifically designated url, but I can't figure out how to.
I tried to upload it to the library, but the file type wasn't accepted, but I fixed that. Once I did get it uploaded to the library, I couldn't change the link.
Also, what do I need to do to make blank01 and blank02 exist without being pages, just categories for now? Or do they have to be pages? | WordPress (or more precisely its `.htaccess` or alternate web server configuration file) passes through requests to existing files.
The easiest way would be to start at root of your site and (using FTP/SFTP/hosting admin panel/etc):
* create `blank01` folder
* create `blank02` subfolder in it
* place `file.xml` into subfolder
And it should just work, link will point to _real_ file and WP won't get involved at all. | stackexchange-wordpress | {

Output before and after the loop
I'd like to hook into the loop, ie. have_posts() maybe? and output some code before and after. Is there a filter for this so I can use it in a plugin without needing to edit themes? | The function `the_post()` (source) triggers the action `loop_start` when it is first used in the loop. This is used in _every_ `WP_Query` loop, so you may want to check if the current query is the 'main' one (assuming that's the query you wish to target)
add_action( 'loop_start', 'wpse107113_loop_start' );
function wpse107113_loop_start( $query ){
if( $query->is_main_query() ){
}
}
The _last time_ `have_posts()` is called it triggers the action `loop_end` (source), so similar to above:
add_action( 'loop_end', 'wpse107113_loop_end' );
function wpse107113_loop_end( $query ){

WordPress doesn't respect the template hierarchy?
My theme has a custom taxonomy template (" **taxonomy-authors.php** ") but WordPress _only_ serves this template file when a term associated with this taxonomy is called. e.g. example.com/cpt/authors/john-doe
When loading example.com/cpt/authors/ it will return a 404. What I want it to do is to list all terms associated with the taxonomy "authors" when example.com/cpt/authors/ is requested.
Here's part of my **taxonomy-authors.php** file:
<?php
if (have_posts()) :
?>
<h2>List of Authors</h2>
<?php
$terms = get_terms('authors');
foreach ($terms as $term) {
echo $term->name;
}
endif;
?>
Any pointers on how to fix this? | There's no such thing as a taxonomy archive. There is a taxonomy term archive, but no taxonomy archive.
E.g. this URL makes no sense in the current system:
example.com/category/

Function filter breaking tag archive menus
Ok, I'm setting up a site with a some CPT's. When creating posts under said CPT's, we added tags. When viewing the posts results after searching, tags were displayed, but upon clicking the archive page indicted that no results were available.
So, I added the code below to my functions.
function myTagFilter($query) {
$post_type = $_GET['type'];
if (is_tag()){
if (!$post_type) {
$post_type = 'any';
}
$query->set('post_type', $post_type);
}
return $query;
};
add_filter('pre_get_posts','myTagFilter');
Now, posts from the CPT's display in the tags archive, but the menu is broken. Here's a link if you want to test it out.
<
So, my question is, why would the menu break because of this? | `is_tag()` is true for the entire tag archive page and for any queries that run on it. You need to restrict that code to only run for the main query on that page and that hte query is a tag query and not some other kind of query, like a menu query. You do that by checking the actual query object being used.
function myTagFilter($query) {
$post_type = $_GET['type'];
if ($query->is_main_query() && $query->is_tag()){
if (!$post_type) {
$post_type = 'any';
}
$query->set('post_type', $post_type);
}
return $query;
};
add_filter('pre_get_posts','myTagFilter');
`is_tag()`, `is_single()`, and other conditionals like that are _functions_ that check the `global` `$wp_query` object. You have to be careful not to use them to check things that are not that `global` object. | stackexchange-wordpress | {

What is the proper way implement a global $wp_rewrite?
The below code works correctly, but I don't know if it is proper coding. Can anyone confirm or comment on the code?
add_action('init', 'news_rewrite');
function news_rewrite() {
global $wp_rewrite;
add_permastruct('news', 'news/%year%/%postname%/', true, 1);
add_rewrite_rule('news/([0-9]{4})/(.+)/?$', 'index.php?news=$matches[2]', 'top');
add_rewrite_rule('^news/([0-9]{4})/?','index.php?post_type=news&year=$matches[1]','top');
} | It is not necessary to define $wp_rewrite in your function. The add_permastruct() and add_rewrite_rule() functions take care of that for you. Try removing the "global $wp_rewrite;" line and see if your code still works.
The add_permastruct() function currently accepts three parameters. There is some backwards-compatibility logic in the function to correct for calls using the old four-parameter structure, but you might want to change that line to use the current three parameter structure, like this:
add_permastruct( 'news', 'news/%year%/%postname%/', array('with_front' => true, 'ep_mask' => 1) ); | stackexchange-wordpress | {

Why is it bad to use the GUID?
I recently upgraded my WP version from 3.2.x to 3.5.x. In the process, the WP functions that retrieve images (wp_get_attachment_image_src, get_the_post_thumbnail, etc) are now broken. I had to change calls to those functions and use `<img src='.$my_post->guid.'>` in order to get it to work.
However, people have told me that using guid is not good. I'm not changing the value though, just using it because I can't find any other way to get my images to load properly. The `wp_get_attachment_image_src` method doesn't return anything. What's so bad about using the guid if it doesn't change? Is it okay in this situation? | In a nutshell - GUID is not supposed to hold meaningful data and the fact that _at this moment_ the data in it happens to be meaningful is coincidental.
WordPress does no verification whatsoever that GUIDs mean anything. They are not guaranteed to stay immutable if you rely on that and they are not changed when that _needs_ to happen if they are treated as data, for example on migration with domain changes.
In all my history of using WP GUIDs were one of very few things that got slapped with backwards incompatible change (sanitizing strategy for them was tightened) and it exploded long deployed work project.
You got very accurate and very practical advice - forget GUIDs exist in WordPress. Follow that advice. | stackexchange-wordpress | {

Can a WordPress administrator see other users' passwords?
Of course, an administrator in WordPress can reset other users' passwords (including that of other administrators). However, can a WordPress administrator **see** other users' passwords? Phrased differently, does the WordPress software protect registered users from an unscrupulous administrator observing their passwords?
Of course, since WordPress is open source, I realize a malicious administrator could hack the software to divulge users' passwords.

Using wordpress and codeigniter in one website
Is it possible to use WordPress as the CMS but all of contents will be displayed using CodeIgniter?
What I want to know also if I can use the WordPress functions by simply including this `wp-blog-header.php` in the CodeIgniter.

Probably one of the function I really need is `apply_filters()` | You can install CI as a theme or a directory in a theme. Then load the files in the theme’s `functions.php` and create the output with CI. You can use all the WordPress code here.
As far as I’m aware there will be no conflicts between CodeIgniter’s reserved names and WordPress.
But I am not so sure about the usefulness of this combination. You will not need most of CI’s code, because WordPress handles that already. | stackexchange-wordpress | {

Author page link in comments is different than in posts?
When I `hover` over the comment author link on my `comments`, it shows a link like <

Here is the snippet:
<a rel="author" href ="<?php bloginfo('url'); ?>/?author=<?php echo $comment->user_id ?>"><?php echo $comment->comment_author?></a> | Use `get_comment_author_link()` instead of `<a href … </a>`:

Highlighting Sub topic in a post?
Have seen this sub topics highlighter in many blogs. It gives a special attraction to a sub topics used in the post.
Is this a plugin or part of code? How can I add this?
| > But am looking for a plugin or a code which can help me with adding this note every time I write a post.
A shortcode to add that "note" is trivial.
function note_sc_wpse_107275($atts,$content) {
return '<p class="note"><strong>'.$content.'</strong></p>';
}
add_shortcode('note','note_sc_wpse_107275');
Then just add `[note]Note content[/note]` to your post body.
That will give you exactly what you see on that site, assuming that I am looking at the right piece of it. By default, it won't look like anything special. You will need to add style rules to decorate it however you like. | stackexchange-wordpress | {

Adding meta boxes to custom post type
The `add_meta_box()` function needs a callback function as an argument to display the meta box on the edit page of a custom type post. My problem is I can not display anything, say in the `input type=text` (for example the values of an already posted post), because I don't have the ID of the post...
`get_post_meta` needs the ID of the post to display the values!
How can I get the ID of the post? | Let’s say your post type is named `product`. You register your metabox with …
add_action( 'add_meta_boxes_product', 'register_product_metabox' );
function register_product_metabox()
{
// register the metabox
}
You get the post id in your callback per post object now:
function metabox_callback( $post )
{
$field = get_post_meta( $post->ID );
}
This happens because WordPress calls the callback with:
call_user_func($box['callback'], $object, $box);

Using get_bloginfo('template_directory') or variable - performance issue
Can I please ask you about the performance of these two approaches in term of execution speed and server load?
**approach 1:**
<img src="<?php echo get_bloginfo('template_directory'); ?>/data1/images/1.jpg">
<img src="<?php echo get_bloginfo('template_directory'); ?>/data1/images/2.jpg" />
<img src="<?php echo get_bloginfo('template_directory'); ?>/data1/images/3.jpg" />
**approach 2:**
<?php $variable= get_bloginfo('template_directory'); ?>
<img src="<?php echo $variable; ?>/data1/images/1.jpg">
<img src="<?php echo $variable; ?>/data1/images/2.jpg" />
<img src="<?php echo $variable; ?>/data1/images/3.jpg" />
The answer to this question will be very useful for me since I meet such cases many times during Wordpress developement. Is the time to get variable content less than the time querying the database for blog info? | There is no performance difference, because the result of `get_bloginfo()` comes from an internal cache anyway, because most (all?) of the return values come from `get_option()` calls, and these are cached internally with `wp_cache_set()` and fetched with `wp_cache_get()`. See Exploring the WordPress Cache API.
Even if there would be a difference it would be too small to be relevant.
The more important difference is readability. This is easier to read and less error prone:
$template_dir = get_template_directory_uri();
foreach ( array ( 1, 2, 3 ) as $n )
echo "<img src='$template_dir/data1/images/$n.jpg' alt=''>"; | stackexchange-wordpress | {

How to remove the option data of a theme when that theme is removed?
I developed a theme which stores some options to the database. I want to delete the option data from the database while the user removes the theme. But I don't know there is any action hook for doing this. Or is there any alternative method to achieve this. | I don't think this is possible with an action hook. You can only Delete a theme from the admin panel after it has been deactivated. Even if an action hook existed for Deleting (not Deactivating) a theme, your theme functions.php would not be running when you are able to hit the Delete link.
Since this is a personal theme for your own use, you can just delete the options whenever you want from the "options" database table using phpMyAdmin or an Options Manager plugin.
An alternative would be to include some sort of Uninstall button on an options page for your theme that would remove the options from the database and deactivate the theme, perhaps either activating TwentyTwelve or letting the user choose which theme to activate after the uninstall is complete. | stackexchange-wordpress | {

Please share your views.. | Copy all of the files to the new folder.
For the database, you'll need to use something like PHPMyAdmin to export the current database as a .SQL file.
Edit the .SQL file you downloaded to remove the first statements specifying what database to use (it will be "USE database").
You'd then need to create a new database using your website's control panel software (like cPanel of Plesk for instance).
Then go to PHPMyAdmin once more, select your new database, and then do an Import, and select the edited SQL file as the file to import.
Then edit wp-config.php in your subdirectory, to use the new database name. | stackexchange-wordpress | {

If child is active add class to parent in customWalker
Im writing a customWalker for the wordpress main navigation area.
But i am a little stuck on how to find and add a class to the parent of the child which is active.
For instance
I have the whole customwalker working perfect, all parents have a active class assigned when they are active, but how to I assign an active class to the parent when a sub class is active?

$class_names = str_replace('current_page_item', 'active', $class_names);
}
But how would I write it for a child class to show the parent an active when the child is active?
Thanks | By default, WordPress applies ancestor classes to the parents of active items. All you have to do is target them via CSS:
.nav-menu li.current_page_ancestor > a,
.nav-menu li.current-menu-ancestor > a {}
This code sample implies that your menu has the `.nav-menu` class. This will work with a navigation menu and with the page menu fallback. | stackexchange-wordpress | {

<input type="text" class="field" name="s" id="s" value="Search or be lost" onfocus="this.value=''" />
</form>
</div>
<!-- END TOP SEARCH -->
Is this possible? | I think japanworm _do not_ want it on the frontpage, the code above let's it display _only_ on the frontpage.
You can exclude something (if not) by putting an ! before the tag. What you want to say is:

Registration Form Shortcode
Is There any way to create a shortcode for registration form using
<?php do_action('register_form'); ?> | `do_action('register_form');` doesn't echo the form. It runs inside the form. You can use it to add information or maybe alter some values... maybe. So the answer is that you can't insert the registration form with that mechanism. And while there are function in `wp-login.php`, the form isn't one of them.
What you probably want is `wp_loginout`.
function loginout_sc_wpse_107419() {
wp_loginout();
}
add_shortcode('loginout','loginout_sc_wpse_107419');
The form itself is not part of any function that you can reuse, so far as I know. The code for it is here, though. You will have to create that form yourself, using that code as a model. | stackexchange-wordpress | {

Checking for 'gallery' shortcode using strpos always returns false
I want to conditionally enqueue a script and stylesheet depending on whether the `[gallery]` shortcode is used in posts. Here is how I am doing it (based on):

if (strpos($post->post_content,'[gallery') === false){
} else {
wp_enqueue_style( ... );
wp_enqueue_script( ... );
}
}
}
add_action( 'wp_enqueue_scripts', 'doraemon_scripts' );
But the problem is, the stylesheet and script aren't being enqueued, as it seems, `strpos` is always returning false. What could I be doing wrong here? | You will need `global $post` to get the `$post` variable into the scope of that function.
function doraemon_scripts() {
if( is_single() ) {
global $post;
if (strpos($post->post_content,'[gallery') === false){
} else {
// wp_enqueue_style( ... );
// wp_enqueue_script( ... );
}
}
}
add_action( 'wp_enqueue_scripts', 'doraemon_scripts' );
Using the `$post` global outside of the Loop is not always reliable, but WordPress will set that variable to the first post in the result set which will be the correct post on _single_ post pages, but won't be right on other pages.
Of course, that won't work if something else has altered the global, and you can't always predict what a plugin will do and where.
You might be safer using ...

Set header for default posts page?
In _Settings/Reading_ I set _Testimonials_ as post page.
How can I change the header of that page? | You could use a template. You just have to copy the file `header.php` and call the new file with the slug of the page `testimonials`. It would require 2 new files :
`header-testimonials.php` and `front-page.php`.
then you can call your custom header with `get_header('testimonials');`
See the template hierarchy. Just be sure Testimonials is your front page.
**EDIT:** Regarding front page (1rst page of the site) WP looks into your theme and the first file to be called is `front-page.php`. Most of the time WP blogs set front page as posts page (reading settings).
Here your can set another file as custom header and call it in `front-page.php` it will be called on front page automatically.
You could also insert some conditional tags in the main `header.php` but it's better to use `front-page.php` when cutomizing front page. | stackexchange-wordpress | {

Is it possible to paste a link without tags and make it directly a link in a post?
So for example: if I post < it won't make it a link if it's a post. If it's comment, it does make it a link... Now, I want it for posts too.. Is this possible, if so, how? Can someone help me with that please? | I use a similar method to the following in a plugin of mine:
function wpse107488_urls_to_links( $string ) {
/* make sure there is an http:// on all URLs */
$string = preg_replace( "/([^\w\/])(www\.[a-z0-9\-]+\.[a-z0-9\-]+)/i", "$1 $string );
/* create links */
$string = preg_replace( "/([\w]+:\/\/[\w-?&;%#~=\.\/\@]+[\w\/])/i", "<a target=\"_blank\" title=\"" . __( 'Visit Site', 'your-textdomain' ) . "\" href=\"$1\">$1</a>", $string);
return $string;
}
I don't use it for post content, but it should work there.
For that, you'd have to employ the `the_content` filter:
add_filter( 'the_content', 'wpse107488_urls_to_links' );
Sidenotes:
This is untested.
The regexes are fairly good, but they will fail in niche cases once in a while. Identifying a URL by format only, while avoiding false positives isn't the simplest of things. | stackexchange-wordpress | {

Insert Message before content of after title

## The Post Title
My custom message | You need to use 'the_content' filter
function add_before_content($content) {

CSS not updating in browser when I change it
I am working on the CSS of my wordpress site. When I make changes and refresh the page the changes are not reflected. When I clear the browser history and cache the changes are still reflected. When I view the source code of the page and look at the css file it has the old content before the change. How do I get this to update so I can develop? | Add a random version number at the end of the css file you are attaching. If you are using 'wp_enqueue_style' or wp_register_style functions, pass a random (version) number `rand(111,9999)` to 4th parameter. If you are attaching css as an html tag, you should add "`?ver=<?php echo rand(111,999)?>`" at the end of the file name. Examples are here
wp_register_style( 'custom-style', get_template_directory_uri() . '/css/custom-style.css', array(), rand(111,9999), 'all' );
or
<link rel="stylesheet" type="text/css" href=" echo rand(111,999)?>">

External/non-WP rewrite rule without QSA
I'm trying to add a new external/non-WP rewrite rule to my `.htaccess` but WP keeps adding `[QSA,L]` to the end of the rule. How do I prevent the QSA part?
This line adds the RewriteRule:
$wp_rewrite->add_external_rule('go/([0-9]+)/?.*$', 'wp-content/plugins/xswpc/redirect.php?id=$1');
And this is the resulting line in my `.htaccess`
RewriteRule ^go/([0-9]+)/?.*$ /wp-content/plugins/xswpc/redirect.php?id=$1 [QSA,L]
What I'd like is:
RewriteRule ^go/([0-9]+)/?.*$ /wp-content/plugins/xswpc/redirect.php?id=$1 [L] | The apache rewrite flags like `QSA` are hard coded, see source. Not sure why it would bother you, but if you really want to change it, then you can and should use the `mod_rewrite_rules` hook for that. Below an example on how to do it:
add_filter( 'mod_rewrite_rules', 'wpse107528_change_mod_rewrite_rules' );
function wpse107528_change_mod_rewrite_rules( $rules ) {
$pattern = '/^(?<=RewriteRule\s\^go.+\$1\s)(\[QSA,L\])$/im';
$replacement = '[L]';
$rules = preg_replace( $pattern, $replacement, $rules );

private functions in plugins

Query multiple tables at once?

Best Practise: Linking to WPMU sites from other sites

For best DB performance should I serialize all theme options together or by type?
If my theme has a lot of options is it better to store all options in one database entry, or to use a databse entry for each group of options?

$template = get_stylesheet_directory().'/archive-cpt.php';

I'm developing a theme that uses the `get_the_category_list()` function (in _category-template.php_ ).
Examining its code, this function calls the `get_the_category()` function (in _category-template.php_ ) which applies the `get_the_categories` filter at the end:
return apply_filters( 'get_the_categories', $categories );
For some strange reason, this filter returns an empty array. If I replace this line with:
return $categories;
then everything is ok.
Any ideas about what's happening here? | Changes occur when a filter is _applied_, but's that's not where the rules for the alteration originate from.
Either your theme or a plugin you are using must be _hooking_ into that filter and be _adding_ a callback function/method, that is responsible for the `$categories` array being emptied.
Deactivate all plugins, switch to a standard theme. Things should be back to normal. Reactivate everything one by one and find the culprit.
Alternatively,
cd /path/to/wordpress/wp-content/plugins/ && grep -r 'get_the_categories' .

My website is getting too many dierect home arechives and this is increasing my bounce rate
My website is getting nearly 800 direct home archives daily, as a result the bounce rate of my website has increased. Usually i get only around 30 home archives a day These hits are not from Google, so how can i stop them. Actually in my Wordpress Jetpack stats my home archives are going around 800 a day which only used to be around 30 a day, so i think some one is giving fake clicks to my website. So the bounce rate of my website is increasing day by day because these hits are not from any of the search engines and most of these home archives are from india and usa. So please help me by providing some way out please. | It sounds like google (and/or other search engines) _could_ have made an error when indexing your site (but I highly doubt it). You shouldn't have that many hit going to your archive pages.
Recovery steps:
Signup for Google Analytics. Use this to determine where those hit are coming from. (GA is more detailed then JetPack Analytics. I've also seen errors in JP's reportings)
Signup for Google Webmaster Tools. This is so you can see how google is hitting your site and what it's indexing. (you can also request that a page not be indexed)

Thanks a lot for your time. | Pagination does not work well will with secondary queries.
First, the ordinary pagination functions depend upon the main query in the `global` variable `$wp_query`. They won't work with secondary queries. There are already a number of questions here about that if you search the site.
Second, trying to paginate secondary queries tends to result in 404 status pages. That is because the query that runs before the template loads-- the "main" query-- is the one that determines what page to load and it _does not_ know about the query written into your template.
I would suggest you use `paginate_links` for your secondary query pagination. There are numerous examples of use here on this site, for example: < | stackexchange-wordpress | {

Query Custom Post by taxonomy multiple categories
I need to query posts using certain taxonomy category, but more than one category of the taxonomy, as I can with posts categories..
For example, I have the **Portfolio** custom posts, and the **Project Type** to organize it (same as categories); So, we have **Animation, draw, icons and painting** types of project. I need to create an loop that will query **animations and painting** types only (query more than one king of portfolio type).
I thinked that tax_query would do it, but this tax_query selects only posts that are in the **animations and paintings at the same time**
My last code was:
$args['tax_query'] = array(
array(
'taxonomy' => 'project-type',
'field' => 'id',
'terms' => array(1,2) // don't work as I need, it's a exclusion)
)
Thank you in advance! | This should give you an `OR` relationship:
$args['tax_query'] = array(
array(
'taxonomy' => 'category',
'field' => 'id',
'terms' => array(1,2),

)
);
As would this:

'field' => 'id',
'terms' => array(1)

array(

'terms' => array(2)

Change query variable for wordpress search

Refresh loop of custom posts (div) after new post is published

foreach($myposts as $post) :
setup_postdata($post);
?>

Auto refresh posts can help my website users to see that when for example somebody submits a post type employer entry, at the same moment all online users can see all updated "employer" posts including that one submitted post. I would like to avoid using plugins.

wp_nav_menu with WP as pure CMS

You _could_ obviously do some rewriting as well, but why go the long way if the solution is simple?

Why does Wordpress search returns same number of results for every search query?

Thanks, Mark | I'm pretty sure that it's pagination problem.
WordPress paginates all queries by default. And default value for `posts_per_page` is 10, I guess.
So if you don't override this parameter and you don't show pagination on your page, then you'll see only 10 results (first page of results).

Normally - if the plugin isn't crap - it pushes through the parameters from PHP to JS using
wp_localize_script( $handle, $object_name, array(
// data
) );
Now this is a smart way of adding your data to a JS script, **but** ... it's not filterable by default. Neither `WP_Scripts` nor `WP_Dependencies` offers _any_ filter users can later utilize
> **Question:** How can we filter the arguments/parameters that are moved from PHP to Javascript using `wp_localize_script`? | `wp_localize_script()` calls the method `localize()` on the global variable `$wp_scripts`. We can set this variable to an instance of a _child_ class of `WP_Scripts`:
class Filterable_Scripts extends WP_Scripts
{
function localize( $handle, $object_name, $l10n )
{
$l10n = apply_filters( 'script_l10n', $l10n, $handle, $object_name );
return parent::localize($handle, $object_name, $l10n);
}
}
add_action( 'wp_loaded', function() {
$GLOBALS['wp_scripts'] = new Filterable_Scripts;
});
The theme customizer doesn’t use that, it creates a separate instance of `WP_Scripts` (see `wp-admin/customize.php`). It might be possible to replace that too:
add_action( 'customize_controls_init', function() {
$GLOBALS['wp_scripts'] = new Filterable_Scripts;
$GLOBALS['wp_scripts']->registered = $GLOBALS['registered'];
});

External stylesheet per page
I want to know if this is a good thing to do. I have many `conditional tags` for `Wordpress pages` and all of them are combined in 1 stylesheet, which is not bad, but I see that the front-page for example does not use 50% of the stylesheet. Is there any reason to use the whole stylesheet? | This approach (one general css) will make your first-load times longer, but when you browse other pages, if the css is cached, everything will be faster.
If you make your stylesheet smaller by splitting them up.. you might have a 'slightly faster' first-page load but every other page that uses another css will still be slower than using one generic css for all pages.
You can minify them if you want as what @JMa have said, you can use caching plugins or even a CDN like cloudflare if you want to make your site faster..

Force wordpress to request for FTP Info on theme/plugin install/update
Is it possible to force wordpress to **always** request for FTP credentials when installing and updating plugins / themes? I know the ftp credentials input is bypassed if wordpress has enough unix user access, but i want wordpress to ask nevertheless. Is this possible? How? | I just tried this on a local install that previously used the 'direct' FS_METHOD.

Extending auth_cookie_expiration based on user role
I'm trying to extend the lifespan of the authentication cookie, but only for administrators.
My code in functions.php is:
add_filter( 'auth_cookie_expiration', 'change_admin_cookie_logout' );
function change_admin_cookie_logout( $expirein ) {
if ($user_id == current_user_can('promote_users')) {
return 60; // yes, I know this is 1 minute
} return 20;
}
The problem I'm having is twofold:
1. When I leave off the else statement, then login fails. In other words, I seem to have to define the expiration time for admins & non-admins, rather than singularly modifying the admin expiration time.
2. the above formula ignores "remember me" and applies it globally. I'd like it to apply only when "Remember Me" is checked.
I've tried tweaking wp_set_auth_cookie but hit some walls and came back to this method. Any help is greatly appreciated! | Untested, but the following should only change the expiration time for admins who select 'remember me'.

$expiration = 60;// yes, I know this is 1 minute

What are the differences between WPINC and ABSPATH?
It's common for plugin developers to protect their plugins from direct access. I saw two ways to do that:
if ( ! defined( 'WPINC' ) ) die;
and
if ( ! defined( 'ABSPATH' ) ) exit;
What are the differences between WPINC and ABSPATH? Which one is the 'right' way to do it? | They are defined as follows:
define( 'ABSPATH', dirname(dirname(__FILE__)) . '/' );
define( 'WPINC', 'wp-includes' );
`dirname` is a PHP function that returns the path of the parent directory, and `wp-includes` is pretty self explanatory.
I would say `ABSPATH` is better because it's one of the first things WP loads and it also looks better:) But there is no real "right way" because they both work. | stackexchange-wordpress | {

get_comment_author_link not working properly
I have this snippet:
<span><a href="<?php bloginfo('url'); ?>/writer/<?php echo get_comment_author_link(); ?>"><?php echo get_comment_author_link(); ?></a></span>
I am displaying the username of the author but it's weird because it works well on the posts... Beneath the post, the username is linked like `/writer/username`, which is fine, but beneath the comment, the username is linked like `/writer/Username`. So for example, a user is called Blackboy 3 , than beneath the post it gets `/writer/blackboy-3`, beneath the comment it gets `/writer/Blackboy 3`. This makes a problem... Because if there is a post called `Blackboy 3`, than the link beneath the comment gets me to the post instead of the `author page`.
Why is this? And how can I solve it? | Simple solution drop this in your `functions.php`
function your_get_comment_author_link () {
global $comment;
if ($comment->user_id == '0') {
if (!empty ($comment->comment_author_url)) {
$url = $comment->comment_author_url;
} else {
$url = '#';
}
} else {
$url = get_author_posts_url($comment->user_id);
}
echo "<a href=\"" . $url . "\">" .get_comment_author () . "</a>";
}
If the user is registered this will link to `/writer/username`, if they are not it will either link to their url or to `#` if they haven't provided one.
Obviously to use it you'll want use it in your code using
<span><?php your_get_comment_author_link() ?></span>

Displaying audio player as preview in audio post in WP3.6

How to make all posts in a category sticky?
Total WP and web development noob here.

if (in_category('bestcategoryever')) {
stick_post(); }
?>

If I change the taxonomy of a post will it get a new time stamp?
I have a category called feature that displays the latest post, but further down the line if the user wants to make an older post a featured post, it doesn't currently work. Using the time stamp would be a good hook to implement this, I'm assuming if the user was to check the feature category on an older post and update, would it get a new time stamp? Therefore I could display the most recent time stamped post? | I am making a couple of assumptions:
1. I assume that by "I have a category called feature that displays the latest post" you mean that you are displaying the latest posts in your "featured" category
2. I assume that your "featured" categories have their own template which has a query that displays them.
Assuming those assumptions to be correct, you need to alter the query that pulls your featured categories so that it sorts by `post_modified` instead of `post_date`. If you will post your query I will show you how to do that. | stackexchange-wordpress | {

stripping tags from excerpt in Wordpress is not working
